SIS Isotonic Gels (Orange) – Fast Energy You Can Take on the Move

When the pace lifts, you need fuel that’s fast, simple, and easy on the stomach. Science in Sport (SiS) Isotonic Gels – Orange deliver 22 g of carbohydrates in an isotonic solution that’s absorbed quickly—so you get clean energy without needing water. Each compact 60 ml sachet provides around 87 kcal with less than 1 g of sugar, giving you the top-up you need to maintain intensity without an overly sweet taste or sticky mouthfeel.

Why this gel works when the effort bites

Isotonic means the gel matches the concentration of your body’s fluids, supporting efficient gastric emptying for rapid uptake. That translates to reliable, comfortable fuelling during tempo runs, interval sets, long rides, and race day—when stopping to sip simply isn’t an option. The zesty Orange flavour stays palatable deep into sessions, while added sodium supports fluid balance as the sweat rate climbs.

Built for runners, cyclists, and triathletes

Slip a few gels into your race belt or jersey pocket and go. The sachets are vegan, gluten-free, and trusted by endurance athletes worldwide, making them a smart fit for any training plan. Whether you’re chasing a marathon PB, ticking off long miles, or sharpening up before a big event, SiS Isotonic Gels help you stay topped up and moving strong.
